Samsung has released a new line of SD and microSD memory cards that focus not only on speed and durability but appearance as well. They come with a brushed metal look in silver or black, and are able pretty dang tough as well:
In order to ensure their reliability, Samsung has designed both lines of memory products to be waterproof, shockproof, and magnet proof, allowing them to withstand some of the harshest conditions. All models are guaranteed to survive up to 24 hours in water, withstand the force of a 1.6 ton vehicle (3,200 lbs), and resist up to 10,000 gauss (slightly less than the power of a medical imaging magnet).
Prices range from $10 to $90 for 2GB to 32GB cards.
